' SPECIFICATION forming part of Letters Patent No. 653,728, dated July17, 1900.

Application filed January 31,1899. Serial No. 704,014. No model.)

- To all whom it may coiwern:

joint is separated the supply of gas, in the case of a gas-bracket, isout 01?.

For purposes of illustration lwill now refer to the annexed drawings, inwhich- Figure 1 is a sectional elevation showing the parts forming thejoint detached; Fig. 2, a sectional elevation showing the parts formingthe joint when in position or engagement; Fig. 3, a side elevation toreduce scale, showing my invention in position; Fig. 4., a plan View ofFig. 2; Fig. 5, a side elevation show- ;ing a pipe provided with aseries of cups and valves.

' Referring to Figs. 1 and 2,-the cup e is provided' with the valve f,which is maintained against the seating by means of the spring g, whichbears upon the carrying socket-piece 2'. This cup -e is secured on therequired pipe in any convenient manner, such as by means of thescrew-thread h. The valve f is of a size to project, as shown, into thecup. The

, ball a is provided with the perforations d,

which communicate with the passage b, and

Ft'ojghis ball a the required article, such as a 'bracken'is, secured bymeans of the screwthread 0 or other suitable arrangement. The weight of,the parts-that is to say, the ball and bracket, &c.- -and the strengthof the sprmg gv are in such a relation to one another that when the balla, carrying the required bracket, is placed in the cup e the spring 9 isovercome and the valve f is thus opened, and i of combustion.

the gas may pass through the joint to the point At the same time a jointis formed between the ball a and the cup e. By this arrangement it willbe seen that in the case of a pipe,-as shown in Fig. 5, having a seriesof cups and valves arranged thereon a bracket may be placed in therequired positionthat is to say, the ball. a, carrying the bracket, maybe removed from cup to cup, as required. When the ball at is removedfrom the cup 6, the spring graises the valve f, and so closes theaperture to the passage of the gas. A

Although for purposes of illustrationl have shown myinvention asarranged so that the valve is carried in the cup, it will be readilyunderstood that, if desired, the valve may be so arranged as to becarried in the ball; but this is a matter of detail.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is-- In joints of the class herein described incombination, a cup in connection with the gas-supply a spring-valvecarried in said cup and having a projection into the interior, a ballhaving perforations and in connection with the outlet, said ball andoutlet branch.

or parts being of sufficient weight to depress the spring-valveaforesaid and allow of the passage of the gas to the outlet or point ofconsumption, said cup and ball being adapted to fit one anothersufficiently tight for the prevention of the escape of gas,substantially as described and illustrated herein and for the purposeset forth.

In testimony that I claim the foregoing l have hereunto set my hand this6th day of December, 189$.
